Aims: This in vitro study was conducted to exam the effect of condensation technique on surface hardness of MTA. Materials and Methods: In this study, 20 acrylic blocks were used. In each block a cubic shape cavity 4 mm in width and 4 mm in depth was prepared. The first group which involve ten samples were filled with MTA using hand condensation method. The other ten samples were filled with MTA using hand method followed by ultrasonic activation for one second after each increment. All samplefatcat:oer3pzb4orcpfhf6o22da5nn4y
